'To all whom 'it may con/cern.' l

Be it known that 1', ALEXANDER Cizoss, a citizen 'of the-United States, residing at Chesterton', in the` county of Porter and State of Indiana', have invented certain new and luseful Improvements in Motor-Flows,

of which the following is a specification.

My invention' relates to vimprovementsin motor plows, and my object is to provide a new and useful 'plow of this character whereby one or more furrows may be simultaneouslyv plowed vand the soil thoroughly pulverized and leveled; also a plow that can be turned around ina coinparativelyshort space.

`In order that the invention may be fully understood, referencewill now be made to the accompanying drawings, in which:

Figure 1'is a side elevation of the p low in plowing position. Fig.-.2 is a plan viewof the plow. Fig, 3 is an irregular, vertical, crois section on' line III- III of Fig. 2. Fig. 4 is an irregular, horizontal, section of part of the steering gear on liiie- I\7.IV of k 1"ig.'3. Fig. 5 isa broken, detail, side elevation of part ofthe steering gear.

'In carrying out the invention, I employ Va znain frame 1, constructed, preferably, of

. channel bars, so that it will be sufficiently strong and rigid to withstand the various strains to which it is subjected.

Frame 1 is carried by a traction wheel 2 and'front wheels 3- and 4. Wheel -4 per- 'forms the function of a land-wheel in regir latin the depth of the two forward'plows 3 in guiding the plow.

Traction wheel 2 is fixeilly-niounted upon a. rear axle 7, jouij'naled in bearings'8 and provided with large fixedly-journaled sprocket wheel t), driven by an endless sprocket chain 10 vrunning around a small sprocket wheel 11 fixed upon a jack-shaft 12,

adapted to be driven from a suitable motor of clutches, etc.,

through the intermediacy (not shown).

lIhe wheel 3'has a peripheral flange 13 to prevent the plow from sliding laterally when on sloping ground. Vhcels 3 and 4 are mounted upon stub axles 14 and 15 provided with forwardly extending crank-arms 1G and 1T, respectively, securedto ay connectingbar 18 provided with a turn-buckle 19, so that it may he lengthened or shortened (i, normallv maintain thev wheels 3 and 4 in parallel position.

6, in addition to Ycoacting with wheelv The stub axles 14 and 15 are pivotally `niounted upon spindles 20 and 2l, spindle 20 being carried in brackets 22-#23 and spindle y21 being carried by brackets Z4-25, respec 50 tively. All of said brackets are secured to the main frame 1. Bracl and 24 are also rigidly connected by a brace 2(ito prevent them froin springing toward or away from each other.

' 65 The stub axles Mrand 15 extend through the bifurcated portions of nuts 27 and 28 mounted upon vertical screws'29 and 30,'v

respectively. Screw 29 is journaled in brackets 22-23 and provided at its upper 70 end with a. hand wheel 31., whereby v it may be rotated to the right or to the left to adjust thev wheel 3 vertically through the intermediacy of nut 2T, which is held from rotating with said screw 29 through its sliding conf- 75 tact with the spindle 20, Fig. 3.

The front wheel 4 is adj usted vertically in the same manner as the front wheel 3, its nut 28 being raised and lowered .through the intermediacy of the screw 30, which is jour- 3o naled in the brackets 24 and 25 and provided Y at its upper end with a hemd-wheel 32 whereby it I nay be rotated either-to the right or left, the nut 28 being'held from rotation with the screw through its sliding contact 85 with the spindle 21. g Y

The connecting-bar 18 is shifted either to the right or left to guidethe wheels 3 and 4,- through the inteiinediacy of a bell-crank lcver 33 pivoted to the brace 26, a connecting- 9,0|

.rod 34 pivotcd atits forward end to lever 33.,

a rack-bar 35 pivoted at one end to the connecting-rod 34 and extending throughguides 36 at its opposite end, a pinion 37 intermeshing with the rack-bar 35 to actuateV the saine, a vertical shaft 38 upon which the pinion 37is rigidly mounted, and a steeringlwheel 39 fixed to the upper end of shaft 38 to rotate the latter either to the right or left. 'I'

40 designates a plow arranged in the rear Y 0f plows 5 and G and to one side of the traction wheel 2, so that a' furrow can he plowed close to a fence and thus avoid the customary waste space between said fence and the adjacent' furrow. y l

Plow 40 is suspended from links l11-42 pivotally connected at their upper ends to Shaft 44 is provided with a xedly-mount- ,fthe main frame 1 through the intermediacy "of stub shafts 43-14 and bearings; L5-16, `respecti vel v. Y

ed hand lever 47 whereby the piontimmy be raised or lowered. Lever i7 is provided with the customary latch 4S enacting with a notched sector 4S) to ylock the lever in any of its adjusted positions.

50 designates a clod pulverizer and soil leveler comprising a hub 51 and spikes radiating from said hub, Hub 51 is mounted upon a shaft-53 carried by a pair of beams 54 pivotally mounted -at their 'forward ends upon a pair of trunnions 55, projecting from opposite sides of the main frime 1. The pulverizer 50 follows in the wake of the plows 5, 6 and 40 and thoroughly breaks up clods left by said plows, and also levels the surface of the soil.

The pulverizer 50 is driven in the same direction as the traction wheel 2 and at a greater speed than the latter, so that it will tend to assist said traction wheel in )ropelling the machine forward instead o ren tarding it.

The driving of the pulverizer is accomplished through the intermediacy of a small sprocket 54 fixedly mounted upon the hub l any of its adjusted positions.

The forward plows are carried on shafts (S1-62 suspended by links (i3- 64, mounted at their upper ends upon shafts @5f-66, journaled in bearings 67-G8, respectively, upon the main frame 1.

Links G3 are fixedly-mounted 'at their upper ends upon the shaft to rock therewith and thus raise and lower the plows 5 and 6.

Shaft (i5 is rocked to raise and lower the plows 5 and (5, through the intermediacy of a crank arm G9 fixed to one end of Said shaft messes 65, a lever 70, and a connecting-rod 71 pivotally secured at its ends to said crank arm 59 and the lever 70.

Lever is fulcrumed upon a stud 72, car-v ried by a notched sector 73, secured to the top of frame 1 to coact with a latch 7l, whereby the lever 70 is locked in any of its adjusted positions.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. 'In a machine of the class described, a frame, a pair of front wheels for supporting the forward end of the frame, upper and lower brackets carried by the spindles having their upper and lower-'ends fixed in the 'respective brackets, nuts having bifurcations slidahly engaging the spindles, screw shafts threaded through the nuts and journaled in the brackets and in spaced parallel relation tothe spindles, stub axles for the wheels, said axles having their inner ends located between and in contact with said bifurcations and pivotally and slidabl)r engaged with said spindles, and means for rotating the screw shafts to raise or lower the nuts.

2.1m combination with'a frame and a pair of front wheels therefor, a pair ofvertical spindles borne by the frame, a, stub axle slidable along the length of each spindle, a pair of rotatable screws journaled in the frame and disposed adjacent the re spective spindles, means on the upper ends ofthe screws to allow the lat-ter to be manually rotated, means slidably mounted on the spindles and in threaded engagement with the screws and actuated by 'the rotatable movements of the latter and connected to said stub axles for raising or lowering the latter, and transverse means on the frame connecting the respective spindles and adjacent screws to hold the spindles and screws against vertical and transverse movements,

frame,A
